AUTOMOBILE-TIRE.

Specification of Letters Patent.

Patented Apr. 25, idiot.

Application filed. March 19, 1910; Serial No. 550,453.

To aZZ whom it may concern;

Be it known that I, GEORGE. E. TOMLIN- SON, a citizen of the United States, residing at Winchester, in the county of Clark and State of Kentucky, have invented a new and-useful Improvement in an Auto-- mobile-Tire, of which the following is a specification. v

This invention relates to certain new and useful improvements in automobile tires, the object being to provide a resilient tire formed of spring metal with a rubber tread, whereby a tire is formed which will have all of the'resilient powers of a pneumatic tire.

A further object of my invention to provide a tire which is so constructed that the same can be readily used in connection with any of the well known makes of wheels using a clencher rim, thereby enabling-the tire to be readily attached to the wheels or an automobile.

Another object of my invention is to provide a tire which is formed of a plurality.

of resilient ring sections so connected together that they will be held in their proper positions without any danger of the sections becoming detached from one another or from the rim of the wheel.

A still further object of my invention is to provide a tire with an elastic tread which serves to cushion the vibration to a certain extent and deaden the noise.

With these'and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts, hereinafter fully described and pointed out inthe claims. v

in the drawing forming a. part of this specificationz-Figure 1 is a sideelevation of a portion of the wheel partly in section showing the constru'ctionof my improved tire. Fig. 2 is a transversesection through the same Fig. 3 is 'a perspective view of the tread fasteningmember. Fig. a is a perspective view of one of the tread sections. Fig. 5 is an inverted plan view of the memher for fastening the section-to the clencher rim.

Referring to the drawing A indicates an automobile wheel having a felly A. and a clencher rim B, of the ordinary construta tion now in use, said rim and felly being provided with registering; openings 18 to receive fastening members for secnringiny improved tire-C in position on the rim,v as

member F which is substantially clencher rim, ll

will be hereinafter fully described. The tlre C comprises a pair of ringvsoctions D and E formed of suitable spring steel and may be formed in a continuous ring or in sections, and are provided with hooked flanges D, E, adapted to coact with the flanges of the clencher rim and with annular depending flanges D E terminating in horizontal portions adapted to contact with. each other and to fit within a ring U-shaped 1n cross section and said ring may be formed of a continuous ring, or in sections accordmg to how the ring sections D and E are formed. The ring sections D and E are concave d annularly, or formed substantially semi-circular in shown. i

Forsecuring the flanges of the ring memhers D and E under the flanges of the provide fastening members G which are adapted to fit down between the flanges. of the ring sections and are provided with. laterally projecting flanges G, which extend over the lower portions of the ring sections, as clearly shown. The fasten ing members (in are provided with threaded bores G adapted to register with the openings of the rim and through which is adapt ed to pass a threaded bolt H which works in the threaded bore, and is clamped by a nut H, and it will be seen by this construction the ring sections will be securely locked to the rim without any danger of becoming accidentally detached.

Arranged within the central annular groove formed by the depending flange portion of the ring sections D and E, is an elastic tread I which may be formed of rubher or any suitable elastic fabric, and is provided with an annular substantially T- shaped groove I, in which the T-shaped heads J of clamping members J are ndapted to fit for securing the tread in position, and said members are provided with bolt portions J which. extend through the flanges of the ring members D and E, and the channel ring F are secured by nuts J and it will be seen that these members secure the meeting edges of the ring sections 'within the channel ring, and the tread in position in such a manner that it will be impossiblev for the parts to become detached after ones being secured in position without loosening the nuts.

cross section, as clearly on any other kind of rim desiredwithout.

4 departing from the spirit of my invention; Having fully described my invention,

Letters Patent is convex spring steel annular ring'sections substantiallysemic rcular in cross section,

flanges at their upper edges terminating in horizontal abutting portions forming an annular groove, a substantially U-shaped annular ring arranged over said flanges, clamping members arranged in said groove extending through said rings provided with T shaped heads, and an elastic tread having a T shaped groove arranged within the groove p of said sections,the heads of the clamping what I claim as new and desire to secure by.

1. A resilient tire comprising a pair of said sections having annular depending members extending into the groove of the tread. I

2. In a resilient tire, the combination with 'a vpair of spring ring members having flanges coacting with the flanges of the clencher rim of the wheel, means for securingsaid rings to said rim, said rings having annular depending flanges terminatin in horizontal portions formin a centra groove, a channel ring adapte to receive. said flanges, a'n elastictread having an annular groove ,in its underside arranged-in the groove of saidsections, and clampingmembers arranged in said grooves .-for securing said flange portions of said ring sections in the channel ring, said members having heads fitting within the groove of the tread for holding said tread in position.
